    PROCESSING AND QUALITY EVALUATION OF WHOLE CANNED ,DWARF' GOLDEN APPLES (SPONDIAS CYTHEREA)

    JOURNAL OF FOOD QUALITY, Issue 1 2002
    DAVID RAMSUNDAR
    ,Dwarf' golden apples (Spondias cytherea) were canned in sucrose syrup of either 30 d,Brix (L) or 40 d,Brix (H). Processing was either by hot filling (HF) of syrup at 92C in filled cans or by steam-exhausting (SE) of the filled cans at 85C for 12,14 min, followed by processing at 100C for 20 min (W20) or 30 min (W30). Sensory evaluation of commercial sterile products, SE-LW30 and SE-LW30 indicated there were no differences (P < 0.05) in appearance, color, taste, aroma and texture. Overall scores indicated that fruits in syrup were liked definitely to like slightly. Panelists indicated that they might or definitely will purchase the products. Fruits in 40 d,Brix syrup were firmer than in 30 d,Brix syrup. By week 8 of storage at 28,30C, pH was stable between 3.6,3.7, and ,cut-out'd,Brix of syrup for LW30 and HW30 products was 24.0 , 24.5 and 28.5, respectively. [source]


    ASSESSING THE CANDIDATE AS A WHOLE: A HISTORICAL AND CRITICAL ANALYSIS OF INDIVIDUAL PSYCHOLOGICAL ASSESSMENT FOR PERSONNEL DECISION MAKING

    PERSONNEL PSYCHOLOGY, Issue 2 2002
    SCOTT HIGHHOUSEArticle first published online: 7 DEC 200
    Although individual assessment is a thriving area of professional practice in industry, it receives little, if any, attention from textbooks on industrial psychology or personnel management. This article is an attempt to establish individual assessment's place in the history of personnel selection, and to examine why the practice has survived despite receiving little attention in research and graduate training. It is argued that the clinical, holistic approach that has characterized individual-assessment practice has survived primarily because the "elementalistic" testing approach, focusing on traits and abilities, has often been dismissed as inadequate for addressing the complexities of the executive profile. Moreover, public displeasure with standard paper-and-pencil testing in the 1960s and 1970s made the holistic approach to assessment an attractive, alternative. The article contrasts individual assessment practice with the current state of knowledge on psychological assessment and personnel decision making. Like psychotherapy in the 1950s, individual psychological assessment appears to have achieved the status of functional autonomy within psychology. [source]


    Whole, Turret and step methods of rapid rescreening: Is there any difference in performance?

    DIAGNOSTIC CYTOPATHOLOGY, Issue 1 2007
    Eliana Borin Lopes Montemor B.Sc.
    Abstract We compared the performance of the Whole, Turret and Step techniques of 100% rapid rescreening (RR) in detection of false-negatives in cervical cytology. We tested RR performance with cytologists trained and among those without training. We revised 1,000 consecutive slides from women participating in an ongoing international screening trial. Two teams of experienced cytologists performed the RR techniques: one trained in RR procedures and the other not trained. The sensitivities in the trained group were Whole 46.6%, Turret 47.4% and Step 50.9%; and in the non-trained group were 38.6, 31.6 and 47.4%, respectively. The , coefficient showed a weak agreement between the two groups of cytologists and between the three RR techniques. The RR techniques are more valuable if used by trained cytologists. In the trained group, we did not observe significant differences between the RR techniques used, whereas in the non-trained group, the Step technique had the best sensitivity. Diagn.

    Whole inactivated virus influenza vaccine is superior to subunit vaccine in inducing immune responses and secretion of proinflammatory cytokines by DCs

    INFLUENZA AND OTHER RESPIRATORY VIRUSES, Issue 2 2008
    Felix Geeraedts
    Background, For protection against (re-)infection by influenza virus not only the magnitude of the immune response but also its quality in terms of antibody subclass and T helper profile is important. Information about the type of immune response elicited by vaccination is therefore urgently needed. Objectives, The aim of the study was to evaluate in detail the immune response elicited by three current influenza vaccine formulations and to shed light on vaccine characteristics which determine this response. Methods, Mice were immunized with whole inactivated virus (WIV), virosomes (VS) or subunit vaccine (SU). Following subsequent infection with live virus, serum antibody titers and Th cell responses were measured. The effects of the vaccines on cytokine production by conventional and plasmacytoid dendritic cells were investigated in vitro. Results and conclusions, In Balb/c mice (Th2 prone) as well as in C57Bl/6 mice (Th1 prone), WIV induced consistently higher hemagglutination-inhibition titers and virus-neutralizing antibody titers than VS or SU. In contrast to VS and SU, WIV stimulated the production of the antibody subclasses IgG2a (Balb/c) and IgG2c (C57BL/6), considered to be particularly important for viral clearance, and activation of IFN-,-producing T cells. Similar to live virus, WIV stimulated the production of proinflammatory cytokines by conventional dendritic cells and IFN-, by plasmacytoid cells, while VS and SU had little effect on cytokine synthesis by either cell type. We conclude that vaccination with WIV in contrast to VS or SU results in the desired Th1 response presumably by induction of type I interferon and other proinflammatory cytokines. [source]


    Effect of processing and storage time on in vitro digestibility and resistant starch content of two bean (Phaseolus vulgaris L) varieties

    JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 12 2003
    Perla Osorio-Díaz
    Abstract Seeds from two commercial bean varieties were cooked and stored for different times and analysed for chemical composition and in vitro starch digestibility. Parallel portions of cooked seeds were dried at 55 °C, milled and stored as flours. In general, protein and ash contents in both samples did not change with storage time, but statistical differences were shown between the two varieties (p < 0.05). Available starch (AS) contents in flours from the ,negro' variety did not change (p < 0.05) with storage time and, in general, were higher than in ,flor de mayo' samples, whose AS levels decreased during storage. The lower AS in ,flor de mayo' flour could be the consequence of formation of resistant starch due to retrogradation. Samples of whole ,negro' seeds did not show differences in AS content at 0, 24 and 48 h of storage compared with the corresponding flours, but at 72 and 96 h the AS increased in the whole samples. ,Flor de mayo' showed a similar pattern in flour and whole samples, with slightly higher values in the whole seeds. In general, total resistant starch (RS) content in the two varieties was higher in the flours than in ,whole' seeds, a fact that is not easy to explain at present. ,Negro' flour presented an RS content around 65.0 g kg,1, and approximately 55.0 g kg,1 was recorded in ,flor de mayo', with slight changes when storage time increased. Whole ,flor de mayo' showed significant levels of the retrograded portion of resistant starch (RRS), which did not change with storage time (p < 0.05). However, values were lower than in the flours. A pattern similar to that of the ,negro' variety was obtained for ,flor de mayo', since the flour exhibited higher amounts of RRS; however, in this variety, the RRS content in ,whole' samples decreased after prolonged storage. Flours presented higher amylolysis rates than whole samples, and the ease of digestion increased with storage time. Copyright © 2003 Society of Chemical Industry [source]


    Combination of bulk storage in controlled and modified atmospheres with modified atmosphere packaging system for chilled whole gutted hake

    JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 6 2001
    Claudia Ruiz-Capillas
    Abstract Whole gutted hake placed in boxes of ice were kept in modified and controlled atmospheres for 12 days with the gas mixture 60%CO2/15%O2/25%N2 (v/v/v) at 2,±,1,°C. Each lot of hake was then subdivided into two other lots and these were packed on trays, some of them in air and some in the same mixture of gases. The trays were kept at 2,°C until spoilage. The shelf-life of the hake stored in these conditions was assessed by physical (pH), chemical (TVBN (total volatile basic nitrogen) and TMA-N (trimethylamine nitrogen)) and sensory (inspection and taste panel) analyses. The results of these analyses indicated that the control lot (stored in air throughout) was rejected before the lots kept in adjusted atmospheres. However, the taste panel accepted all the lots, including the control lot, after 24 days of storage. The sample which was kept at 2,°C in a controlled atmosphere for 12 days and then packed in a modified atmosphere of the same gas mixture did not exceed pH 7 after 31 days of storage, nor the limits of TVBN and TMA-N of 40 and 12,mg per 100,g respectively. As regards oxidative rancidity, TBA (2-thiobarbituric acid) levels were very low under all storage conditions and did not exceed 2.5,mg malonaldehyde per 100,g muscle. According to the results of this study, bulk storage of whole gutted hake in boxes in ice under a controlled atmosphere could be combined with later packaging in a modified atmosphere on trays stored at 2,°C to extend the shelf-life of the hake. © 2001 Society of Chemical Industry [source]


    Ultrastructure of cyst shell and underlying membranes of three strains of the brine shrimp Artemia (Branchiopoda: Anostraca) from South India

    MICROSCOPY RESEARCH AND TECHNIQUE, Issue 12 2006
    V. Sugumar
    Abstract The cyst of Artemia has shell and membranous coverings over the embryo. The membranous coverings have special adaptive features to allow the physical changes accompanying repeated hydration and dehydration cycles that might occur and adversely influence postembryonic development. Whole and slices of cryptobiotic cysts were processed for electron microscopy to study the internal details and to compare the morphological architecture of three Artemia strains of South India. Surface topography of scanning electron microscopic (SEM) studies revealed distinct button shaped structures on the cyst of Puthalam strain. Transmission electron microscopic (TEM) studies of the cysts displayed the conventional pattern of anostracan crustaceans with outer cortex and alveolar layer, cuticular membranes, and the cytoplasmic inclusions namely nucleus, yolk droplets, lipoid bodies, and mitochondria. The prominent wavy outer cortex layer of Puthalam cysts corroborates the results of SEM studies. Microsc. Res. Tech. © 2006 Wiley-Liss, Inc. [source]

    Prospective Evaluation of Intraoperative Hemodynamics in Liver Transplantation with Whole, Partial and DCD Grafts

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 8 2010
    M. Sainz-Barriga
    The interaction of systemic hemodynamics with hepatic flows at the time of liver transplantation (LT) has not been studied in a prospective uniform way for different types of grafts. We prospectively evaluated intraoperative hemodynamics of 103 whole and partial LT. Liver graft hemodynamics were measured using the ultrasound transit time method to obtain portal (PVF) and arterial (HAF) hepatic flow. Measurements were recorded on the native liver, the portocaval shunt, following reperfusion and after biliary anastomosis. After LT HAF and PVF do not immediately return to normal values. Increased PVF was observed after graft implantation. Living donor LT showed the highest compliance to portal hyperperfusion. The amount of liver perfusion seemed to be related to the quality of the graft. A positive correlation for HAF, PVF and total hepatic blood flow with cardiac output was found (p = 0.001). Portal hypertension, macrosteatosis >30%, warm ischemia time and cardiac output, independently influence the hepatic flows. These results highlight the role of systemic hemodynamic management in LT to optimize hepatic perfusion, particularly in LDLT and split LT, where the highest flows were registered. [source]


    Capitalism's Anxious Whole: Fear, Capture and Escape in the,Grundrisse

    ANTIPODE, Issue 5 2008
    Vinay Gidwani
    Abstract:, Two Hegels inhabit the,Grundrisse. The first is conservative of the "selfsame" subject that continuously returns to itself as non-identical identity and propels "history". The other Hegel tarries with the "negative" he (which or variously calls "non-being", "otherness""difference") to disrupt this plenary subject to Marx's reading of a Hegel who is different-in-himself lends,Grundrisse its electric buzz: seizing Hegel's "negative" as the,not -value of value, i.e. "labor", Marx explains how capital must continuously enroll labor to its will in order to survive and expand. But this enrollment is never given; hence, despite its emergent structure of necessity, capital's return to itself as "self-animating value" is never free of peril. The most speculative aspect of my argument is that the figure of "labor" in,Grundrisse, because of its radically open formulation as not-value, anticipates the elusive subject of difference in postcolonial theory, "the subaltern",that figure which evades dialectical integration, and is in some ontological way inscrutable to the "master". Unexpectedly, then,Grundrisse gives us a way to think beyond the epistemic and geographic power of "Europe". [source]


    Enzyme and acid treatment of fish meal for incorporation into formulated microbound diets for barramundi (Lates calcarifer) larvae

    AQUACULTURE NUTRITION, Issue 2 2009
    L. NANKERVIS
    Abstract This study reports on two experiments in which the use of enzyme- and acid-treated fish meal were evaluated for incorporation into formulated microbound diets for barramundi (Lates calcarifer) larvae. In the first experiment, partially hydrolysed fish meal was used to determine whether partial hydrolysis increased the dietary value of fish meal used in microbound diets fed to L. calcarifer larvae. Total length and dry weight at the end of the experiment were both higher for larvae fed diets containing untreated fish meal than those fed diets containing any level of hydrolysate. Larval survival ranged from 15.8% to 47.2% but there were no significant differences between treatments (Fig. 3; P > 0.05). Carcass pepsin levels of larvae fed diets containing untreated fish meal were significantly higher than pepsin levels of larvae fed all other diets (P < 0.05). The second experiment determined the effects of incorporating graded levels of denatured fish meal (DF) into microbound diets for L. calcarifer larvae. Acid treatment increased the digestibility of fish meal approximately twofold when compared with intact fish meal. Larvae fed diets containing 45% DF had significantly higher total length and dry weight at the end of the growth trial than those fed a diet containing only intact fish meal. Larval survival ranged from 30.2% to 58.2%, with no significant differences between treatments. Whole homogenate pepsin levels were significantly affected by the level of dietary DF inclusion with larvae fed diets containing a greater proportion of intact fish meal containing higher pepsin levels. There was a significant correlation between dietary DF inclusion level and decreasing pepsin level (r2 = 0.569, P < 0.01); however, larval pepsin level did not correlate to either dry weight or total length (Pearson correlation, P > 0.05). The results of this study are a valuable contribution to our understanding of factors influencing the utilization of ingredients in microbound diets developed for marine fish larvae and will facilitate development of more effective formulated foods for them. Figure 3. ,Mean (±SE) survival of barramundi larvae fed experimental diets containing fish meal hydrolysed for varying period (7.5,60 min), from 14 to 28 days after hatching. Means with different superscripts are significantly different (P < 0.05). [source]


    Nutritional value of feed peas (Pisum sativum) in practical diet formulations for Litopenaeus vannamei

    AQUACULTURE NUTRITION, Issue 2 2002
    D.A. DAVIS
    Dry peas of mixed Canadian prairie varieties which were commercially obtained and processed to provide a variety of meals were evaluated in practical shrimp feeds. Whole and de-hulled peas were pin milled to produce raw flours. A portion of these meals were processed to produce whole extruded and de-hulled extruded meals. Additionally, a portion of the whole pea meal was processed by infrared cooking to produce a micronized meal. The five meals were evaluated in practical diets for Litopenaeus vannamei under controlled laboratory conditions. The first experiment was designed to estimate apparent protein and energy availability of the various meals. Using a practical reference diet, the meals were substituted using a 70:30 ratio to produce the test diets. Based on contrasts, both extruding and micronizing the pea meals resulted in significant improvements in both apparent protein digestibility and apparent energy digestibility values. Apparent energy digestibility values for the various ingredients expressed as percentage ± SD were: whole raw, 72.3 ± 8.1; whole extruded, 86.0 ± 8.9; de-hulled raw, 88.4 ± 4.4; de-hulled extruded, 94.4 ± 10.0; whole micronized, 94.1 ± 10.2. To evaluate the response of shrimp to the diets containing pea meal, two 7-week growth trials were conducted in the laboratory using a practical diet formulated to contain 360 g kg,1 protein and 90 g kg,1 lipid. In the first growth trial the shrimp had a mean initial weight of 0.66 g and six test diets were evaluated that included the basal diet and five diets for which the pea meals were included in the diet at 250 g kg,1 dry weight replacing whole wheat. In the second growth trial the shrimp had a mean initial weight of 1.1 g and only the whole raw and whole extruded meals were evaluated at 50, 100 and 200 g kg,1 inclusion in the diet. At the conclusion of the first growth trial weight gain ranged from 718 to 862% and at the conclusion of the second growth trial weight gain ranged from 394 to 502%, with no significant differences or discernible trends observed as a result of the various dietary treatments. Based on the observed results, the continued evaluation of feed peas as a potential ingredient of shrimp feeds is warranted. Additionally, if feed peas are suitably priced, commercial producers are encouraged to evaluate feed peas as an alternative protein and energy source. [source]


    Reporting on Service Efforts and Accomplishments on a Whole of Government, Basis

    AUSTRALIAN ACCOUNTING REVIEW, Issue 25 2001
    R. G. Walker
    The United States' Governmental Accounting Standards Board has fostered the development of reports on "service efforts and accomplishments". The SEAs framework for classifying performance indicators and providing accompanying contextual data and interpretative commentary was adopted in New South Wales, but developed through its application on a "whole of government" basis and the adoption of distinctions between "program outcomes" and "community outcomes". The whole-of-government approach has the potential to provide a more consistent track record of public-sector performance in the face of departmental restructuring or the shifting of programs or subprograms between agencies.

    Biomass distribution and nitrate assimilation in response to N supply for Vitis vinifera L. cv. Cabernet Sauvignon on five Vitis rootstock genotypes

    AUSTRALIAN JOURNAL OF GRAPE AND WINE RESEARCH, Issue 3 2002
    AYALSEW ZERIHUN
    Abstract Effects of nitrogen (N) supply on biomass distribution as well as N effects on NO3"assimilation, were examined in two-year-old graftlings of Vitis vinifera L. cv. Cabernet Sauvignon on five rootstocks. Whole-plant biomass in all graftlings more than doubled with increased N supply in solution from 0.25 to 8 mM. Whole plant biomass was also affected by rootstock genotype, but to a lesser extent than by N supply. Biomass allocation to roots declined with increased N supply for all stock-scion combinations, but the magnitude of that response varied with rootstock genotype. Nitrate reductase activity (NRA) in leaves increased with increased N supply for all stock-scion combinations, whereas root NRA increased only up to 1 mM N supply, dropping markedly with additional N. NRA in leaves was one to two orders of magnitude higher than NRA in roots - a difference that increased steadily with increased N supply. By implication, grapevine leaves have a much higher capacity for NO3 - - reduction than do grapevine roots, and any contribution by roots to whole-vine NO3 - - assimilation declines even further as NO3 - - availability increases.

    From Parts to Wholes: Mechanisms of Development in Infant Visual Object Processing

    INFANCY, Issue 2 2004
    Gert Westermann
    Visual object processing in infancy is often described as proceeding from an early stage in which object features are processed independently to a later stage in which relations between features are taken into account (e.g., Cohen, 1998). Here we present the Representational Acuity Hypothesis, which argues that this behavioral shift can be explained by a developmental decrease in the size of neural receptive fields in the cortical areas responsible for object representation, together with a tuning to specific object features. We evaluate this hypothesis with a connectionist model of infant perceptual categorization. The model shows a behavioral shift in featural to relational processing consistent with similar results observed in the infant categorization experiments of Younger (1985) and Younger and Cohen (1986).

    Illustrative White Matter Fiber Bundles

    COMPUTER GRAPHICS FORUM, Issue 3 2010
    Ron Otten
    Abstract Diffusion Tensor Imaging (DTI) has made feasible the visualization of the fibrous structure of the brain white matter. In the last decades, several fiber-tracking methods have been developed to reconstruct the fiber tracts from DTI data. Usually these fiber tracts are shown individually based on some selection criteria like region of interest. However, if the white matter as a whole is being visualized clutter is generated by directly rendering the individual fiber tracts. Often users are actually interested in fiber bundles, anatomically meaningful entities that abstract from the fibers they contain. Several clustering techniques have been developed that try to group the fiber tracts in fiber bundles. However, even if clustering succeeds, the complex nature of white matter still makes it difficult to investigate. In this paper, we propose the use of illustration techniques to ease the exploration of white matter clusters. We create a technique to visualize an individual cluster as a whole. The amount of fibers visualized for the cluster is reduced to just a few hint lines, and silhouette and contours are used to improve the definition of the cluster borders. Multiple clusters can be easily visualized by a combination of the single cluster visualizations. Focus+context concepts are used to extend the multiple-cluster renderings. Exploded views ease the exploration of the focus cluster while keeping the context clusters in an abstract form. Real-time results are achieved by the GPU implementation of the presented techniques.

    A Fast Simulation Method Using Overlapping Grids for Interactions between Smoke and Rigid Objects

    COMPUTER GRAPHICS FORUM, Issue 2 2008
    Yoshinori Dobashi
    Abstract Recently, many techniques using computational fluid dynamics have been proposed for the simulation of natural phenomena such as smoke and fire. Traditionally, a single grid is used for computing the motion of fluids. When an object interacts with a fluid, the resolution of the grid must be sufficiently high because the shape of the object is represented by a shape sampled at the grid points. This increases the number of grid points that are required, and hence the computational cost is increased. To address this problem, we propose a method using multiple grids that overlap with each other. In addition to a large single grid (a global grid) that covers the whole of the simulation space, separate grids (local grids) are generated that surround each object. The resolution of a local grid is higher than that of the global grid. The local grids move according to the motion of the objects. Therefore, the process of resampling the shape of the object is unnecessary when the object moves. To accelerate the computation, appropriate resolutions are adaptively-determined for the local grids according to their distance from the viewpoint. Furthermore, since we use regular (orthogonal) lattices for the grids, the method is suitable for GPU implementation. This realizes the real-time simulation of interactions between objects and smoke.

    Detecting particle swarm optimization

    CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 4 2009
    Ying-Nan Zhang
    Abstract Here, we propose a detecting particle swarm optimization (DPSO). In DPSO, we define several detecting particles that are randomly selected from the population. The detecting particles use the newly proposed velocity formula to search the adjacent domains of a settled position in approximate spiral trajectories. In addition, we define the particles that use the canonical velocity updating formula as common particles. In each iteration, the common particles use the canonical velocity updating formula to update their velocities and positions, and then the detecting particles do search in approximate spiral trajectories created by the new velocity updating formula in order to find better solutions. As a whole, the detecting particles and common particles would do the high-performance search. DPSO implements the common particles' swarm search behavior and the detecting particles' individual search behavior, thereby trying to improve PSO's performance on swarm diversity, the ability of quick convergence and jumping out the local optimum. The experimental results from several benchmark functions demonstrate good performance of DPSO. Copyright © 2008 John Wiley & Sons, Ltd. [source]


    Clustering revealed in high-resolution simulations and visualization of multi-resolution features in fluid,particle models

    CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 2 2003
    Krzysztof Boryczko
    Abstract Simulating natural phenomena at greater accuracy results in an explosive growth of data. Large-scale simulations with particles currently involve ensembles consisting of between 106 and 109 particles, which cover 105,106 time steps. Thus, the data files produced in a single run can reach from tens of gigabytes to hundreds of terabytes. This data bank allows one to reconstruct the spatio-temporal evolution of both the particle system as a whole and each particle separately. Realistically, for one to look at a large data set at full resolution at all times is not possible and, in fact, not necessary. We have developed an agglomerative clustering technique, based on the concept of a mutual nearest neighbor (MNN). This procedure can be easily adapted for efficient visualization of extremely large data sets from simulations with particles at various resolution levels. We present the parallel algorithm for MNN clustering and its timings on the IBM SP and SGI/Origin 3800 multiprocessor systems for up to 16 million fluid particles. The high efficiency obtained is mainly due to the similarity in the algorithmic structure of MNN clustering and particle methods. We show various examples drawn from MNN applications in visualization and analysis of the order of a few hundred gigabytes of data from discrete particle simulations, using dissipative particle dynamics and fluid particle models. Because data clustering is the first step in this concept extraction procedure, we may employ this clustering procedure to many other fields such as data mining, earthquake events and stellar populations in nebula clusters.

    From Red Lists to Species of Conservation Concern

    CONSERVATION BIOLOGY, Issue 6 2004
    VERENA KELLER
    aves; conservación de especies; listas rojas; prioridades de conservación; Suiza Abstract:,National red lists of threatened animal and plant species prepared according to the criteria of the World Conservation Union (IUCN) adequately reflect the extinction risk of species within a country but cannot be used directly to set conservation priorities. In particular, the significance of national populations for the conservation of the species as a whole is not taken into account. We present a procedure that can be used to assess national responsibility based on the national red-list status of a species, the international importance of the national population, and the species' "historical rarity" status. We distinguished five responsibility classes for breeding birds: B1, threatened species with internationally important populations in Switzerland; B2, threatened species with internationally less important populations; B3, nonthreatened species with internationally important populations; B4, nonthreatened species with internationally less important populations; and B5, species that have never been common in Switzerland. Two responsibility classes were distinguished for birds occurring in Switzerland as visitors: G1, species with large concentrations in Switzerland and an unfavorable conservation status in Europe, and G2, species with large concentrations in Switzerland and a favorable conservation status in Europe. Two additional classes (G3 and G4) for visiting species occurring in internationally less important numbers are possible but were not analyzed in detail. Responsibility classes B1, B2, B3, G1, and G2 were defined as species of national conservation concern. We developed the method for birds in Switzerland, but it can be used in other countries and for other taxonomic groups as well. It is particularly suitable where national red lists are established according to IUCN guidelines. Resumen:,Las listas rojas nacionales de especies de animales y plantas amenazadas que siguen los criterios de la World Conservation Union (IUCN) reflejan adecuadamente el riesgo de extinción de especies en un país pero no pueden ser utilizadas directamente para definir prioridades de conservación. En particular, no se toma en cuenta el significado de poblaciones nacionales para la conservación de especies como tales. Presentamos un procedimiento que se puede utilizar para evaluar la responsabilidad nacional con base en el estatus de lista roja de una especie en un país, la importancia internacional de la población nacional y el estatus de "rareza histórica" de la especie. Distinguimos cinco clases de responsabilidad para aves residentes: B1, especies amenazadas con poblaciones internacionalmente importantes en Suiza; B2, especies amenazadas con poblaciones internacionalmente menos importantes; B3, especies no amenazadas con poblaciones internacionalmente importantes; B4, especies no amenazadas con poblaciones internacionalmente menos importantes; y B5, especies que nunca han sido comunes en Suiza. Se distinguieron dos clases de responsabilidad para aves que ocurren como visitantes en Suiza: G1, especies con grandes concentraciones en Suiza y un estatus de conservación desfavorable en Europa y G2, especies con grandes concentraciones en Suiza y un estatus de conservación favorable en Europa. Son posibles dos clases más, (G3 y G4) para especies visitantes que ocurren en números menos importantes internacionalmente, pero no fueron analizados en detalle. Las clases de responsabilidad B1, B2, B3, G1 y G2 fueron definidas como especies de interés nacional para la conservación. Desarrollamos el método para aves en Suiza, pero también se puede utilizar en otros países y con otros grupos taxonómicos, Es particularmente adecuado donde las listas rojas nacionales se establecen de acuerdo con lineamientos de IUCN.

    This procedure is intended to increase population size without introducing exogenous genes into the managed population. Previous work examining the genetic effects of a single generation of supportive breeding has shown that although a successful program increases the census population size, it may reduce the genetically effective population size and thereby induce excessive inbreeding and loss of genetic variation. We expand and generalize previous analyses of supportive breeding and consider the effects of multiple generations of supportive breeding on rates of inbreeding and genetic drift. We derived recurrence equations for the inbreeding coefficient and coancestry, and thereby equations for inbreeding and variance effective sizes, under three models for selecting captive breeders: at random, preferentially among those born in captivity, and preferentially among those born in the wild. Numerical examples indicate that supportive breeding, when carried out successfully over multiple generations, may increase not only the census but also the effective size of the supported population as a whole. If supportive breeding does not result in a substantial and continuous increase of the census size of the breeding population, however, it might be genetically harmful because of elevated rates of inbreeding and genetic drift. Resumen: La práctica de apoyar poblaciones silvestres débiles mediante la captura de una fracción de los individuos silvestres, su cautiverio para la reproducción y la liberación a su descendencia en habitas naturales para que convivan con organismos silvestres se conoce como reproducción de apoyo y se ha empleado ampliamente en la biología de la conservación y en el manejo de pesca y vida silvestre. Este procedimiento tiene la intención de incrementar el tamaño de la población sin introducir genes exógenos en la población bajo manejo. Trabajos previos sobre los efectos genéticos de una sola generación de reproducción de apoyo muestran que, aunque un programa exitoso incrementa el tamaño poblacional, puede reducir la población genéticamente efectivae inducir así un exceso de consanguinidad y pérdida de variación genética. Expandimos y generalizamos análisis previos de la reproducción de apoyo y consideramos los efectos de múltiples generaciones de reproducción de soporte en las tasas de consanguinidad y de deriva génica. Derivamos ecuaciones de recurrencia para el coeficiente de consanguinidad y de coancestría, y por tanto ecuaciones de tamaños efectivos de consanguinidad y de varianza, para tres modelos de selección de reproductores en cautiverio : aleatoria, preferentemente entre los nacidos en cautiverio y preferentemente entre los nacidos en libertad. Los ejemplos numéricos indican que la reproducción de apoyo, cuando es exitosa en múltiples generaciones, puede ser favorable para el incremento no solo del tamaño, sino del tamaño efectivo de la población soportada en su conjunto. Sin embargo, si la reproducción de soporte no resulta en un incremento sustancial y continuo del tamaño de la población, puede ser genéticamente dañina debido a las altas tasas de consanguinidad y de deriva genética.

    Analysis of allergens in metalworking fluids

    CONTACT DERMATITIS, Issue 5 2008
    Maj-Len Henriks-Eckerman
    Background:, Metalworking fluids (MWFs) are well-known causes of occupational contact dermatitis in machinists. Objective:, To gain information about skin sensitizers in MWFs and to compare it with the information in safety data sheets (SDSs). Methods:, A total of 17 samples of MWF concentrates were analysed for skin sensitizers known or suspected to be used in MWF. Alkanolamines, formaldehyde, isothiazolinones, methyldibromo glutaronitrile (MDBGN), and iodopropynyl butylcarbamate (IPBC) were separated by liquid chromatography. Resin acids of colophonium (colophony) were separated by gas chromatography. The substances were identified with mass spectrometric detection and ultraviolet detection. Results:, Of the MWFs, 15 contained 6,39% of alkanolamines, mostly monoethanolamine and triethanolamine. Formaldehyde was detected in all MWFs: the concentrations of total formaldehyde ranged between 0.002% and 1.3%. Benzisothiazolinone and octylisothiazolinone were detected in one fluid each. IPBC was detected in nine MWFs, and the highest concentration was 0.09%. Methylisothiazolinone and MDBGN were not detected in any of the fluids. Resin acids of colophonium were detected in seven MWFs in concentrations ranging from 0.41% to 3.8%. On the whole, the allergens analysed were poorly declared in the SDSs. Conclusions:, The content of total formaldehyde was not declared in any SDS. IPBC, a relatively new allergen, seems to be common in MWFs. Isothiazolinones may be relevant allergens of machinists, and they should be analysed in MWFs in case other sources are not identified. The occupational relevance of positive patch test results to MWF ingredients in machinists is difficult to determine if information in the SDSs is relied upon. [source]


    BUSINESS METHOD PATENTS AND U.S. FINANCIAL SERVICES

    CONTEMPORARY ECONOMIC POLICY, Issue 3 2010
    ROBERT M. HUNT
    A decade after the State Street decision, more than 1,000 business method patents are granted each year. Yet, only 1 in 10 is obtained by a financial institution. Most business method patents are also software patents. Have these patents increased innovation in financial services? To address this question, we construct new indicators of research and development intensity based on the occupational composition of financial industries. The financial sector appears more research intensive than official statistics would suggest but less than the private economy taken as a whole. There is considerable variation across industries but little apparent trend. There does not appear to be an obvious effect from business method patents on the sector's research intensity. Looking ahead, three factors suggest that the patent system may affect financial services as it has electronics: (1) the sector's heavy reliance on information technology, (2) the importance of standard setting, and (3) the strong network effects exhibited in many areas of finance. Even today litigation is not uncommon; we sketch a number of significant examples affecting financial exchanges and consumer payments. The legal environment is changing quickly. We review a number of important federal court decisions that will affect how business method patents are obtained and enforced. We also review a number of proposals under consideration in the U.S. Congress. (JEL O31, O34, G20) [source]


    Geriatric Emergency Medicine and the 2006 Institute of Medicine Reports from the Committee on the Future of Emergency Care in the U.S. Health System

    ACADEMIC EMERGENCY MEDICINE, Issue 12 2006
    Scott T. Wilber MD
    Abstract Three recently published Institute of Medicine reports, Hospital-Based Emergency Care: At the Breaking Point, Emergency Medical Services: At the Crossroads, and Emergency Care for Children: Growing Pains, examined the current state of emergency care in the United States. They concluded that the emergency medicine system as a whole is overburdened, underfunded, and highly fragmented. These reports did not specifically discuss the effect the aging population has on emergency care now and in the future and did not discuss special needs of older patients. This report focuses on the emergency care of older patients, with the intent to provide information that will help shape discussions on this issue. [source]


    Emission Intensity Enhancement of DC Arc Plasma Induced by External Oscillating Magnetic Field

    CONTRIBUTIONS TO PLASMA PHYSICS, Issue 10 2007
    M. M. Stoiljkovi
    Abstract Direct current (dc) arc plasma with continuous aerosol supply was coupled with an external oscillatingmagnetic field of a few tens of mT and a frequency of up to 1 kHz. Such configuration was used to alter the plasma-related radiative properties. The magnetic field was oriented perpendicularly to the electric field in the plasma and forced the arc column to oscillate as a whole with respect to the surrounding atmosphere. The magnitude of the appliedmagnetic.eld controls the amplitude of the oscillatory motion. Several parameters that can contribute to the radiative properties of the plasma were investigated (arc current, composition of aerosol introduced into the plasma, amplitude and frequency of the magnetic field applied). Spectral emission from different zones of the plasma column was measured by optical emission spectroscopy (OES). In comparison to steady-state plasma, the applied magnetic field induces an intensity enhancement of emission of the most analytes considered. The intensity enhancement is strongly affected by the amplitude and frequency of plasma column oscillations, i.e. by plasma column velocity. Also, intensity enhancement depends on the plasma zone observed. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source]


    The Coming Transformation of Shareholder Value

    CORPORATE GOVERNANCE, Issue 1 2005
    Simon Deakin
    This essay challenges the primacy of shareholder value. Shareholder primacy originates not in company law, but rather in the norms and practices surrounding the rise of the hostile takeover movement in Britain and America in the 1970s and 1980s. It is less strongly institutionalised than might be supposed, because it is essentially a cultural rather than a legal point of reference. Moreover, in the course of the past decade, a shift in the content of shareholder value has occurred which reflects the stakeholder critique of that period: this reflects the idea that shareholders should exercise their power not as representatives of the market, but as agents of society as a whole. The corporate governance of the future will be centrally concerned with how this idea is worked out in practice. [source]


    Inhibition deficits of serious delinquent boys of low intelligence

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 5 2007
    Roos Koolhof
    Introduction,Studies have shown that low intelligence (IQ) and delinquency are strongly associated. This study focuses on inhibitory deficits as the source for the association between low IQ and delinquency. Further, the authors explore whether serious delinquent boys with a low IQ are exposed to more risk factors than serious delinquent boys with an average to high IQ. They also examine the extent to which low IQ and higher IQ serious delinquents incurred contact with the juvenile court because of their delinquent behaviour. Methods,Cross-sectional and longitudinal data from the Pittsburgh Youth Study were used to constitute four groups of boys: low IQ serious delinquents (n = 39), higher IQ serious delinquents (n = 149), low IQ non-to-moderate delinquents (n = 21) and higher IQ non-to-moderate delinquents (n = 219). Results,Low IQ serious delinquents committed more delinquent acts than higher IQ serious offenders. Low IQ serious delinquent boys also exhibited the highest levels of cognitive and behavioural impulsivity. There were no differences between low IQ and higher IQ serious delinquents on measures of empathy and guilt feelings. Instead, elevations on these characteristics were associated with serious offenders as a whole. Compared with higher IQ serious delinquents, low IQ serious delinquents were exposed to more risk factors, such as low academic achievement, being old for grade, depressed mood and poor housing. Conclusions,Inhibition deficits appear important in the aetiology of delinquency, especially among low IQ boys. Serious delinquent boys are all impulsive, but the higher IQ serious delinquents seem to have a better cognitive control system. Interventions aimed at low IQ boys should focus on the remediation of behavioural impulsivity as well as cognitive impulsivity. Copyright © 2007 John Wiley & Sons, Ltd. [source]


    The Higher Education Policy Institute (HEPI) Report Summaries

    CRITICAL QUARTERLY, Issue 3 2004
    Anthony Smith
    These reports are useful summaries of a quantity of research undertaken over a course of years by the independent HEPI research unit, based in Oxford. They are researched responses to the range of issues and questions which have been current in UK higher education over the last five or six years. Future social historians will surely discern, through their tiny print and clear thought, the growing instrumentality of this era, the nervous concern of the authorities, as costs rise, to ensure that university education brings economic benefit to the nation as a whole.

    The Role of Interest in Fostering Sixth Grade Students' Identities As Competent Learners

    CURRICULUM INQUIRY, Issue 1 2000
    Jean C. Mcphail
    The combined works of John Dewey and Jerome Bruner provide a framework spanning a century of educational thought which can inform curriculum decisions concerning students' educational development, especially for middle school students whose waning of motivation toward school has been well documented by researchers and has long concerned parents and teachers. This framework, combined with recent contributions of motivation and interest researchers, can create broad understandings of how to collaboratively construct effective educational contexts. As early as 1913, Dewey specifically looked at the pivotal role of students' genuine interests in Interest and Effort in Education. Our current research focus on how students' interest can inform curricular contexts marks the recent shift showing an increased use of interest in education research since 1990. In this article, we discuss our study of a team-taught double classroom of sixth grade students whose interests were determined through a series of brainstorming sessions, and individual and focus group interviews. Students' interests fell into six categories centering around subject areas such as Drama, Science, and Animal Studies. Learning contexts were constructed around four of these subject areas. Students participated in their first or second choice of subject area group. We found significantly higher scores on measures of Affect and Activation if students participated in their first choice group. We found intra-group unities of preferred and dispreferred ways of learning which distinguished each group from the class as a whole. Finally, our findings indicated that students reliably described their genuine interests over time. Students' interests were found to be effective tools for informing curriculum decisions in the creation of sixth grade learning contexts. [source]


    COMMENTARY: Silver Bullet Junkies and the Codifiers That Love Them: Behavioral Roots Behind a Legacy of Bad Modeling and Use

    DECISION SCIENCES, Issue 2 2008
    Elliot Bendoly
    ABSTRACT As research continues to evolve, it is important to look back with a critical eye on its impact on practice and what is guiding its trajectory into the future. In this work we discuss some of the key behavioral drivers that taken as a whole have made for a less than ideal relationship between research, model development, and use/reliance in practice. From a general public-good perspective, there is an obvious need for academics to take on a greater role of responsibility when it comes to both research and curriculum in an effort to avoid some of the failings that our past work has inevitably encouraged to date.
